GRAIN-SHOCKER.

Application filed September 18, 1918.

To all whom it may concern:

Be it known that I, CHARLES W. Arms, a subject of the King of Great Britain, residing at Eyebrow, in the Province of Saskatchewan and Dominion of Canada, have invented certain new and useful Improvements in Grain-Shockers; and I do hereby declare the following to be a full, clear, andexact description of the'invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The object of the invention is-to provide a practical and eflioient grain shocking mechanism adapted to receive the bundles from the harvester during the progress of the latter and after a sufiicient number of bundles have been accumulated to form a shock to deposit the latter in an upright position upon the ground, the body of the shock being compressed so that it may be properly secured and retained until such time'as it maybe suitable to remove it tothe barn or other point of deposit, and a further object ofthe invention is to provide means for the indicated purpose which maybe controlled with the minimum effort upon the part of the operator and the minimum disturbance of the shock in the removal of the machine therefrom after it has been deposited as indicated upon the ground.

Further objects and advantages will appear in the course of the following description, it being understood that changes in form, proportion and details may be'resorted to, within the scope of the appended claims,' without departingfrom the spirit of the invention.

In the drawings:

vention the'main frame 10, having sidebars or members connected at their front ends by a cross bar 11 and at their rear ends by an arch 12, is supported by ground wheels 13 mounted upon stub axles'l r, while in bear ings 16 arranged at opposite sides upon the main frameare mounted the spindles 17 01 a tilting receptacle 18 enlarged toward its outlet end and adapted to receive the bundles which are to constitute the shock, said spindles 17 forming the axis upon which the re ceptacle is adapted to tilt from the normal position indicated in Fig. l to the discharging position indicated in Figs. 3 and 4.

Mounted in cooperative and tilting relation with the receptacle is a guard fork hav ing a head 19 provided with tines 20 which in the normal or receiving position of the receptacle serve to span and closethe open dlscharging end thereof, and supportlng 7 arms 21 which extendlongitudinally of the receptacle and are slotted as at 22 to'receive the spindles 17 of said receptacle so that while the fork has a tilting movement with the receptacle it is also capable-of a longitudinal movement relative to the receptacle as hereinafter explained. Abrace rod 23 is shown extending from an intermediate portion of each supporting arm 21 to the head of the fork to stiffen the structure.

The receptacle at each side is provided with a fork returning or replacing arm 24 having a laterally projectingpin 25'and-in connection with this fork returning pin there is arranged a spring catch 26 consisting of yieldingvjaws arranged in the path of said pin and adapted to engage the latter when the receptacle and fork are in'their normal or loading positions.

Also carried by the fork is a guide 'arm 27 provided with a terminal'p'in 28, preferably having an anti-friction'sleeve' or-roller 29 mounted thereon, said pin being adapted to traverse a curved dumping traok' dwhich is arranged in a bracket3l depending from the side bar of the main supporting frame and arranged concentric or approximately concentric with the axis of the receptacleso thatas the latter swings fromits normal position to the dumping position shown in dotted lines in Fig. 4. saidguide pin '28 traverses the track 30 and the fork head retains'its position relatively to the mouth or open end of the receptacle so as to retain the' 'undles in theiatter; However; said iii) track 80 terminates short of the limit of movement of said fork and of the back of the bracket 31, and when the guide pin 28 reaches the limit of said track it drops and thus permits the fork to drop until the guide pin is checked by a lower or replacing track 32 forming a part of said bracket 31., or said fork comes in contact with the ground as shown in Figs. 3 and 4. The track 30 which may be referred to hereinafter as the dumping track for the reason that the guide 28 traverses the same during the dumping movement of the fork and receptacle, is pivotally mounted at 33 and bears at its free end upon the front side of the }1 tCl 6t 31 as shown at 34 and though the guide pin will pass to the dumping track during the downward or. dumping movement of the fork, when the fork is raised to its normal position by the contact of the pin 25 with the supporting arm 21 due to the return of the pan to the receiving or normal position, theguide pin 28 will traverse the return track 32 and in passing the free end of the dumping track will displace the free end of the latter as shown by the dotted lines in Fig. i. Obviously, after the guide pin has passed the free end of the dumping track the latter will return to its normal position so as to properly guide said pin during the succeeding downward movement incident to a later dumping action of the fork and receptacle.

The action of the fork and receptacle therefore may be described as involvino swinging or pivotal movement thereof positions thereof being relatively retained,

' with the fork head. closing the mentholopen end ofthe receptacle, until the 1: r

reaches substantially a vertical position whereupon the fork will drop abruptly until checked, as above noted, by the contactof the fork head with the ground or the contact of the guide pin 28 with the return track 32, thus forcibly depositing the shock upon the ground and-firmly seatin it in an upright position with all of the stalk butts on the. ground or settled to a proper position, and as the receptacle is moved in its return operation it will carry with it the fork which by reason of the guide track 39, is returned toits proper position relative to the recep tacle the guide pin 28 bein carried beyond the free end of the dumping track 30, and said fork being locked with the receptacle in the receiving position by the engagement of the pin 25 with the catch or clamp 26.

It is desirable to forcibly compress the stalks in the receptacle during the dumping operation so as to render the shock compact and reduce it at the-upper portion to insure a stable seating upon the ground, and to this end there are employed .side compressor arms 35 pivoted as at 36 to the fork head and having pivotally mounted elements 87 yieldingly held in proper relation with the compressor arms by springs 38 and carrying between said elements a compressor band or strap 39, the latter being adjustably connected with the elements 37 to provide for variation to suit different heights or lengths of stalks, and a similar adjustment being provided at 40 for the pivotal connection between said elements and the coml ressor arms. Connected with the compressor arms are guide armsl, slotted as shown at 4-2 for the reception of guide pins L3, preferably provided with anti-friction sleeves or rollers 44, said guide pins being carried by bracket arms 45 rising from the main frame 10. As the fork is swung from the normal position indicated in Fig. 1 to the dumping position indicated in Figs. 8 and 4, the compressor arms, by reason of the cooperative action of the slotted guide arms ll and the pins 43, are swung inwardly toward the pan to brin the compressor strap or band 39 into shock compressing relation with the top of the receptacle, said pivotal yielding elements 37 which carry the strap or band 39 swinging into the receptacle as indicated in Fi s. 3 and 4. Obviously, this compressor mechanism is restored to its normal position by the return of the fork and receptacle to the normal or receiving position and thus disposed out of the way to avoid interfering with the deposit of the stalks in the receptacle in the course of forming the shock.

Various means may be employed for moving the receptacle and fork from the normal to the dumping position and returning the same, but for the present purposes it has been deemed sufficient to show the stub axle and spindle at one side of the machine provided with sprocket wheels 46 and 47 connected by a chain48 for moving the receptacle and fork in one direction and the gears 49 and 50 in mesh to move the said parts in the opposite direction, a clutch being ar ranged between the sprocket wheel as and the gear wheel 49 and having its movable or shiftable member 51 keyed upon the axle'as shown at 52 and adapted for engagement with either the sprocket wheel or said gear. Any suitable means may be employed for conveniently shifting this clutch member as required bythe operation of the mechamsm. i i

Also any desired form of elevator orconveyer may be employed to conduct the bundles of grain to the pan from the binder (not shown) such as that shown in my former Patent #1233355, and indicated in dotted lines in the drawings hereof. (See Fig. 2.) 7
